NORTHERN CALIFORNIA — Caltrans is alerting motorists that the north- and southbound Interstate 5 Maxwell safety roadside rest areas, or SRRA, in Colusa County have reopened.

The Maxwell rest areas had been closed the past year for upgrades to the wastewater and water systems.

Meanwhile, Caltrans is reminding motorists that the neighboring north- and southbound Willows rest areas in Glenn County will remain closed for construction through Dec. 31.

During the Willows closure, northbound I-5 motorists will be directed to use the Corning SRRA in Tehama County, about 25 miles north of the Willows Rest Area.

Southbound motorists will be directed to the Maxwell SRRA in Colusa County, about 27 miles south of the Willows Rest Area.

Caltrans is investing $13.8 million to update the wastewater and water systems at the Maxwell and Willow rest areas. TSI Engineering Inc. of North Highlands, Sacramento County, is the contractor for both projects.

Weather or unexpected events may delay or prolong the work. Caltrans advises motorists to “Be Work Zone Alert.” The department will issue construction updates on Twitter @CaltransDist3 and on Facebook at CaltransDistrict3.
